One instance cited by Vanity Fair is the abrupt cancellation of Trump's meeting with Mexico's President Enrique Peña Nieto, which Kushner had reportedly spent numerous hours trying to negotiate.

According to writer Emily Jane Fox, a source said about Kushner, "I'd never once heard him say he was angry throughout the entire campaign. But he was furious."

In addition to issues surrounding Mexico, Kushner, an Orthodox Jew, has also been blasted for working on behalf of an administration that recently barred refugees when his own grandmother was a Holocaust survivor.

In fact, Trump has indicated that his son-in-law could help brokering peace in the Middle East, citing his family background, but critics have pointed out the Kushner is too inexperienced for the task, reports The Guardian.

Meanwhile, his wife Ivanka has also been under fire for posting an Instagram picture of her and Kushner dressed in fancy clothes as protests about her father's immigration order grew.

According to USA Today, she has been accused by many on social media as being "tone deaf."
